Gu,
I am inclined to believe both of your issues have to deal with the paper.
The spots you comment on for the first print I've encountered as a result
of sizing/buffering in the paper.
The second print i think is just a really really flat print. If you
notice there is no contrast in your step wedge but it does not get to Dmax
until the very last step, the rest are not quite at Dmax but have no
contrast in them. But then your first square is pretty close to white but
not quite. So, there is probably a little bit of over exposure going on
here but overall your neg does not have enough contrast in it for this
TYPE of paper.
If you are using digital negs then it would be very easy to correct these
problems. That is tweek the neg for this type of paper, especially if you
are using Mark's system.
I would not hair dry rather just let air dry.
Is the paper hot pressed or cold pressed? My first cyanotypes were on cold
pressed paper and I got spots because the paper could not stand up to the
washing and little pieces flaked off.
I actually really like overexposed prints for cyanotype and then bleaching
them with washing soda. I often will overexpose my prints just so i can
bleach them cause it's fun and i like the images i get with this. Then I
tone with a tea of some sort, etc.
